STRAINER FRSiNS.

SPECIFICATION' forming part of Letters Patent, No. 333,343, dated December 29, 1885.

Application tiled November-13, 1885. Serial No, lsloii. (No model.)

To @ZZ whom t may concern:

Beit known that I, CHRISTIAN II. Serrurier, of the city, county, and State of New York, have invented a new and useful Improvement in Strainers for Sinks; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to the strainers in cast-iron sinks.

The strainers over the discharge-opening in cast-iron sinks are frequently fastened in place by means of the bolts which secure the collar connecting the waste-pipe with the sink, the bolts being made fast by means of nuts upon their lower ends. These nuts soon become rusted upon the bolts, so that the bolts must needs be cut in order to remove the strainer. In cutting the bolts the whole joint of the wastepipe with the sink is broken and must be remade when the strainer is replaced.

The object of my invention is to avoid these u difficulties, and to facilitate the removal of the strainer, when required, without disturbing the joint made between the waste-pipe under the strainer with the sink.

4In the accompanying drawings, Figure l is a plan View of a portion of a sink illustrating my improved attachment of a strainer thereto Fig. 2, a similar view with the strainer removed; Fig. 3, a central transverse sectionin line a: x of Fig. 1.

A represents a portion of the cast-iron sink, constructed with a flanged discharge-openin g, B, Fig. 3, of the customary form.

C is the waste-pipe, and D the collar by which the end of the waste-pipe is upheld in place to overlap and encircle the downwardlyprojcting flange e about the discharge-opening E E are the sink-bolts by which the collar D is upheld and made tight. These parts are all formed and united in the customary manner, a putty joint being made between the end of the waste-pipe()` and the flange e. Instead, however, of passing the outer ends of the sink-bolts E E, which hold the collar, through holes in a strainer resting upon the shoulder f, encircling the edge of the opening B in the sink, as is usually the case, so that thestrainer shall be confined by the heads ot Said bolts,

tlnegbolts are carried through the ends of a- The edge of thc strainer is notched or cut in at diametrically-opposite points to tit the oft'- scts formed by the shoulders t' i, so that the strainer may rest upon said shoulders t 'i and upon the corresponding shoulder, j", on. the sink, as shown in Figs. 2 and 3. The depth of the rabbet inthe sink and the bar forming the shoulders t t' and f is such as to bring the surface et' the strainer flush with that of the sink when the strainer is titted in place. (See Fig. 3.) A tapering nut, K, of brass, phosphorbronze, or other non-oxidizable metal, preferably angular in cross-section, is inserted in a counterpart tapering opening pierced with its widest end downward in the middle of the bridge-bar G. A counter-sunk hole is `formed in the center of the strainer I-I, and the strainer is secured in place over the bridge-bar by a screw, Il, ot' brass or bronze, passed through said opening, and which is screwed into the nut li. As the screw is tightened,it operates not only to make fast the strainer, but also to tighten up the tapering nut in its seat.

To remove the strainer, it is only necessary to withdraw the screw L, the joint of the waste-pipe with the sink remaining meanwhile intact.

The use of my invention involves no change in the customary forms of sinks, and my improved device may be readily applied thereto, ior the bridge-bar G tits upon the customary shoulder about the opening in the sink,and is secured therein, instead ot' and in the same manner and with the saine eiiect-so far as the fastening of the collar D and the closing ofthe 'fjoiiit made thereby are involved-as an ordinary strainer. The strainer itself is only IOO altered so far as to have notches or sections cut out in its edge to embrace the offsetsvforiing the shoulders iz on the bridge-bar. rIhe bridge-bar is comparativelyinexpensive, consisting ofasimple casting having a tapering brass nut fitted in an aperture cored out in the middle of its length. The device consequently admits of wide application and general use at comparatively slight cost.

I do not claim, broadly, a screwand crossbar,in combination with the strainer over the outlet of a sink, as such a device has been heretofore constructed; but

I claim as my invention- 1. The combination, with a sink, the collar encircling the ange of the wasteopening therein, and the sink-bolts by which the collar is upheld and made fast thereto, of a bridgebar, whose ends,resting upon the shoulder encircling the waste-opening, are conned by the sink-bolts, and a strainer, which, resting upon in the bridgebar,with its base downward, and

a screw passing through an aperture in the strainer to engage the small end of the nut,

substantially in the manner and for the purpose herein set forth.

In testimony whereof I have signed my name 1 to this specification in the presence of two subscribing witnesses.

CHRISTIAN H. SCHRACK.
